Overview

ISO 3684:1990/Amd 1:2006 - Conveyor belts - Determination of minimum pulley diameters - is an international amendment to the 1990 ISO 3684 standard. It clarifies the application of the original standard for determining the minimum pulley diameters used with conveyor belts. The 2006 amendment explicitly states that the standard is not applicable to light conveyor belts as described in ISO 21183-1 (Light conveyor belts - Part 1: Principal characteristics and applications). The document was prepared by ISO/TC 41 (Pulleys and belts), Subcommittee SC 3 (Conveyor belts).

Key Topics

The amendment and parent standard focus on the practical and engineering aspects of pulley sizing for conveyor belts. Key technical topics and considerations covered or implied by the standard include:

• Minimum pulley diameter determination to ensure belt performance and longevity
• Factors affecting pulley selection such as belt construction, flexibility and bending behavior
• Operational influences like load, speed and service conditions that affect required pulley diameters
• Compatibility between pulley design and conveyor-belt materials to minimize fatigue and premature wear
• Standardization of measurement approaches and terminology for consistent pulley sizing across suppliers and users

Note: The amendment does not provide new numerical values or formulas in this extract; it clarifies scope exclusions (light conveyor belts).

Applications

ISO 3684:1990/Amd 1:2006 is used where safe, reliable and repeatable pulley sizing is required for industrial conveyor systems. Typical users and practical applications include:

• Conveyor designers and mechanical engineers specifying belt and pulley systems
• Conveyor manufacturers and component suppliers ensuring product compatibility
• Maintenance and reliability teams selecting replacement pulleys to prevent belt damage
• Safety and compliance officers referencing standards for procurement and conformity
• Standards bodies and testing laboratories harmonizing test methods and specifications

Using the standard helps reduce belt fatigue, improve belt life, and ensure consistent performance across conveyor installations.

Related Standards

• ISO 21183-1 - Light conveyor belts - Part 1: Principal characteristics and applications (explicitly referenced by Amendment 1 as out of scope)
• ISO/TC 41 (Pulleys and belts) publications and related conveyor-belt standards (for broader context and complementary guidance)

For anyone working on conveyor design or belt selection, referencing ISO 3684 along with ISO 21183-1 (for light belts) provides clearer scope and helps ensure the right pulley-sizing approach for the intended belt type.
